Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mechanical parking device, and particularly to a device for reducing the installation frontage or width of a vertical circulation parking device.

[Prior Art] Mechanical parking devices aim to increase the number of cars that can be accommodated by efficiently utilizing space in three dimensions, and to eliminate the need for parking outside in cities, and have recently become extremely popular. It is widely known that this is happening. Among these parking devices, vertical circulation parking devices are the most commonly used.

As is well known, the vertical circulation parking system circulates a chain endlessly between sprocket wheels that are pivotally installed in the upper and lower positions. Chain arms extend from the chain at predetermined intervals, and A carrier is suspended near the tip of each chain arm via a suspension shaft. After accommodating a car at the entrance, the carrier is operated in circulation with a chain to store the vehicle, or to call out necessary items to the entrance.

By the way, it goes without saying that it is desirable to efficiently install such a parking device in as small a space as possible or on a site, but there is a particular desire to reduce the width or frontage of the parking device. In other words, due to its nature, a parking device is used for entering and exiting cars, so the entrance and exit face the road.
However, in commercially prosperous areas with high land prices where such mechanical parking devices can be financially viable, the portion of land facing the walkway is an absolute requirement. Allocated to other uses such as stores, offices, etc.
This is because there is a strong desire to compress the frontage used for parking devices. Or, the frontage of the land you own may be too small to install a parking device.

[Problems to be Solved by the Invention] There are the following reasons why it is difficult to meet such requests by reducing the width and frontage.

First, in the vertical circulation parking system @101 as shown in FIG. 9, the chain 10
A drive device 141 for driving the carriages 11 on both sides
Therefore, the width of the entire vertical circulation parking device 101 is the same as that of the carrier 110.1.
It is clear that a dimension is required that is the sum of the width of 10 mm and the width of the drive device 141 plus a necessary margin.

Next, when designing such a parking device 101, the dimensions of the carriers 110 and 110, the pitch of the chain 105, the pitch between the carriers 110 and 110, and the sprocket wheel 1
There is a mutual correlation between the diameter of 03 or 104 and the length of chain arm 106, etc., and there are many constraints that prevent free selection of design dimensions, but those skilled in the art generally understand that 1'iJ A design configuration that approximates the desired one is established from within the possible range.

One such constraint is the length of the chain arm 106. If the installation width of the drive device 141 can be reduced in the above case, then the length of the chain arm 106 can be shortened to bring the carriages 110, 110 closer to each other, thereby reducing the overall frontage of the parking device. Although it is clear that the chain arm 106 can be reduced in size, generally speaking, when the chain arm 106 is shortened, the sprocket wheel 1
When the carriages 110, 110, etc. orbit near 03 or 104, an interference phenomenon occurs in which the adjacent carriages 110 and 110 invade a wide range of mutual areas, and the parking device cannot be established. be.

As mentioned above, despite the large demand for installing vertical circulation parking devices on sites or installation areas with smaller frontage than the conventional standard, due to the above-mentioned constraints, there has been no conventional method to accommodate this. I couldn't do it.

In response to such circumstances, the present invention has been made with the objective of providing a vertical circulation type parking device that can be installed even in narrow spaces.

[Means for Solving the Problems] In response to the above-mentioned object, the present invention supports a suspension shaft on which a carrier is suspended so as to be slidable along a chain arm, and controls the carriage by a guide rail to move the carrier. The installation width of the parking device is reduced without causing interference between the carts inside.

That is, in the present invention, a chain is endlessly chained and circulated between sprocket wheels pivotally installed at upper and lower positions, and a carrier is suspended via a suspension shaft from a chain arm inserted in the chain chain. In a vertical circulation type parking device that accommodates automobiles by moving the carrier along with the circulation of the chain, the chain arm has a slit hole opened between the base side position P and the tip side position Q, and the chain arm The shaft is slidably inserted into the slit hole, and guide rollers are pivotally attached to both ends of the suspension shaft, while the guide rollers are rolled and guided to the fixed side position of the parking device. A guide rail having a straight section and a curved section is provided, and the guide roller is guided by the guide rail toward a position P on the trunk side of the chain arm in the straight section, and in the curved section. In the narrow width vertical circulation system, the chain arm is guided toward the tip side position Q, and the position of the carrier is controlled together with the suspension shaft to reduce the equipment width of the parking device. It is configured as a parking system.

[Function] In the straight section where the carrier moves up and down, the guide rollers are forced inward by the guide rail, and the suspension shaft is biased towards the base side of the slit hole in the chain arm, thereby reducing the interval in the vertical movement path of the carrier. This makes it possible to reduce the width of the vertical circulation parking device. On the other hand, near the sprocket wheels at the upper and lower ends, the curved guide rail forces the guide rollers outward, and the suspension shaft is biased toward the tip of the chain arm slit hole, which increases the distance between the carriers. To eliminate interference between carriers or reduce it to an acceptable range.

[Example] Hereinafter, the configuration of the apparatus of the present invention will be explained with reference to the drawings.

FIGS. 1A and 1B show the entire vertical circulation parking device 1. FIG. Sprocket wheels 3, 3 and 4, 4 are pivotally installed at upper and lower positions in the area of the device or within the shaft 2, and a chain 5.5 circulates endlessly between these sprocket wheels 3.4 and 3.4, respectively. It is suspended. Chain 5.
Although link chains are used for each of the links 5 and 5, illustration of individual links is omitted in the figure. At each fixed link interval of the chain 5.5, arms 6a, 5
A chain arm 6.6 with extension a is inserted. The chain arm 6.6 has a slit hole 7 along the longitudinal direction of the chain arm 6 from the trunk side position P to the tip side position Q, as shown in the detailed view of this part in FIG.
A hole is passed through the hole, into which a suspension shaft 11 is inserted.

FIG. 2 shows the configuration of the carrier 10, and a plurality of carriers 10 are used, and as a general rule, those having the same height are used. The carrier 10 is assembled by placing and fixing a tray 16 between the suspension frames 15.15, into which a car is to enter, and is pivotally suspended from the suspension shaft 11 at the bearing portion 12.12 of the suspension frame 15.15. It is something. The suspension shaft 11 is further inserted through slot holes 7, 7, each of which has an elongated opening or split, in the chain arm 6.6, and furthermore, both shaft ends 13.13 of the suspension shaft A guide roller 14, 14 is rotatably mounted on each of the guide rollers 14,14. The guide rollers 14, 14 are for rolling on the transfer surfaces 21a, 22a, 23a of each guide rail as the carrier 10 moves.

Next, on the fixed position side, there are an outer guide rail 21.21 and an inner guide rail 22.22, 2 as guide rails.
3.23 is provided.

As shown in FIG. 1(A), the outer guide rail 21 extends vertically downward from the level position near the upper sprocket wheel 3 as the starting point, detours around the lower sprocket wheel 4, turns around, and then The guide rollers 14 are fixedly installed in an elongated U-shape with the end point extending vertically upward and again at a level position near the sprocket wheel 3. The guide roller 14 is guided from the outside of the circulation path to regulate its position. The upper inner guide rail 22 is arranged in an upwardly convex arc shape near the upper part of the sprocket wheel 3, and guides or supports the guide roller 14 from the inside of the circulation path by transferring the guide roller 14 to the transfer surface 22a. The location is regulated by Further, the lower inner guide rail 23 is arranged in a downwardly convex arc shape near the bottom of the sprocket wheel 4, and guides or presses the guide roller 14 from the inside of the circulation path with the transfer surface 23a to regulate the position. ing.

FIG. 4 shows the correlation between the circulation path or locus of the guide roller 14 and the slit hole 7 of the chain arm 6 and each guide rail, which is necessary for the present invention. First, the chain arm 6 shown in the third figure will be described.

The chain arms 6 are inserted at regular intervals or pitches in the chain of the chain 5, and have arms 6a extending in a direction perpendicular to the direction of the chain of the chain 5.
A slit hole 7 is opened in the direction a over a length S from the trunk side position P to the tip side position Q, and the suspension shaft 11 passes through this as described above.

FIG. 4 is a schematic diagram showing the correlation of the entire device.

A chain 5 is stretched in circulation between the sprocket wheels 3 and 4. A, B, C, D...■ in the diagram.

J. What is shown by a chain line that returns to 8 after passing through each point is the locus or circulation path 8 of the guide roller 14.

Here, there is a straight line between points △, B, and C, and C, D, E,
F is an arc with a radius of curvature R centered at a length S of the slit hole 7 from the center of the sprocket wheel 4;
The section between G, , and 8 is a straight line, and the section between H, 1, J, and the sprocket is a circular arc with a radius of curvature R centered above the center of the wheel 3 by the length S of the slit hole 7.

Between points A, B, and C in the figure, and between points F, G, and 8, the guide roller 14 is guided inward by the outer guide rail 21, so that the guide roller 14 is connected to the suspension shaft 11.
is moving upward in the direction of the trunk side position P of the slit hole 7. Therefore, the distances X between the circulation paths 8 and 8 in the straight sections between A, B, and 0 and between F, G, and 8 are approaching each other.

Next, between the curve sections C, D, E, and F forming circular arcs, the center of the sprocket wheel 4 and the radius of curvature R (-
Since it is eccentric by the length S from the center of and the guide roller 14,
The suspension shaft 11 is upwardly displaced within the slit 7 from the trunk side position P to the tip side position Q. At point D in the figure, the guide roller 14 to the suspension shaft 11 are located near the middle between the base side position P and the tip side position Q of the slit hole 7, and at the point E, they are at the tip side position Q. Similarly E
, between points F, the guide roller 14 or the suspension shaft 11
is gradually returned from the tip side position Q to the trunk side position P.

Also, regarding the curve section H, 1, J, and A points forming a circular arc, the center of the sprocket wheel 3 and the center of the radius of curvature R (-X/2) of the path 8 are eccentric by the length S. Therefore, as the guide roller 14 gradually moves from point H toward point 0, it is supported and guided by the inner guide rail 22, and the guide roller 14 and the suspension shaft 11 move through the slit hole 7 from the base side position P to the tip side position Q. It moves and is displaced from point 0 toward point A, and returns from position Q on the tip side toward position P on the trunk side.

In addition, in the case of this configuration, if a drive device is not provided between the carriages 10 and 10, and there is a gap between the carriages 10 and 10 at which at least the transmission shaft 41 is provided, for example, as shown in FIG. The drive device 40 can be disposed at an appropriate position such as at the rear of the shaft 2.

As described above, in the vertical circulation parking device 1 of the present invention, the carriage 10 is pivotally attached to the suspension shaft 11 that is slidable within the slit hole 7, and the guide pivoted to the suspension shaft 11 is The rollers 14 are guided by an outer guide rail 21, inner guide rails 22, 23, etc. Therefore, as the suspension shaft 11 to the guide roller 14 circulate, they slide through the slit hole 7 while being regulated by the guide rail at that position, and the position within the slit hole 7 is determined.

Here, as shown in FIG. 1(A) and FIG. The hole 7 is regulated to be closest to the trunk position P, and therefore the interval X between the circulation paths 8 and 8 is close to each other. This means that the distance between the left and right carriages 10.10 is getting closer, and the vertical circulation parking device 1
This means that the overall frontage or width of the area is small.

Next, in the curved sections between points C, D, E, and F and between points H, I, J, and A, the guide rollers 14 and the suspension shaft 11 are connected to the outer guide rail 21 and the inner guide rail 23, or the inner guide rail. 22, it moves in the direction of the distal end side position Q of the slit hole 7 or takes the most distal position Q. That is, the carrier 10 is connected to the sprocket wheel 4 or 3.
When passing nearby, they take a long detour or a long detour.

By taking such a long detour or detour, mutual interference between the carrier 10 and the next adjacent carrier 10 in the circulating section is improved.

Figures 5(a) and 5(b) are for explaining this situation. FIG. 5(A) shows the state around the lower sprocket wheel 4 in the case of the apparatus of the present invention. The upper carrier 10B (10) has guide rollers 14
The suspension shaft 11 is located at a position P on the trunk side of the slit hole 7 and is suspended. Lower adjacent carrier 10A (10)
In this case, the guide roller 14 and the suspension shaft 11 are suspended in the vicinity of the position Q on the tip side of the slit hole 7, that is, the guide roller 14 and the suspension shaft 11 are suspended from the sprocket wheel 4.

Here, the interference area 17 shown with diagonal lines between the carrier 10A (10) and the carrier 10B (10) is a small area,
There is some oscillation in the carriers 10A (10) and 10B (10), and there is no risk that the carrier 10B (10) will come into contact with the car 18 stored in the carrier 10Δ(10) and cause damage. . It is well known to those skilled in the art that the occurrence of such a narrow interference area 17 is tolerable even in conventional vertical circulation parking systems, and that there is no problem based on numerous operational results. It is as it is.

Next, in order to compare with the above, in FIG. 5(A), a slit hole is not provided in the chain arm 6', and the suspension shaft 11' is fixed at a position corresponding to the trunk side position P in the above case. A case in which the carrier 10' is suspended is shown for comparison.

Here, the upper carrier 10B'(10') is suspended from a suspension shaft 11' at a fixed position of the chain arm 6'.

On the other hand, the downwardly adjacent carrier 10A'(10') also has a suspension shaft 11 at the fixed position of the chain arm 6'.
’ is suspended. Here, the interference area 18!17' shown with diagonal lines, which occurs between the carrier 10A'(10') and the carrier 10B'(10'), is clearly large.
The carrier 10B'(10') is the carrier 10A'<1
0') and collided with the automobile 18'. It is clear that such a design is not practical.

In other words, in the device of the present invention shown in FIG. 5(A), when the carrier revolves around the sprocket wheel 4, the apparent radius of rotation around the sprocket wheel 4 increases, and the carrier moves away from the adjacent carrier. As it revolves around while avoiding,
Circulation can be performed with minimal or no mutual interference.

Further, this also holds true in the vicinity of the sprocket wheel 3.

Another embodiment based on the above-mentioned typical configuration will be described.

In FIG. 6, all the parts labeled with the same numbers as those shown in FIG. 1 have the same structure.

Here, only the guide rail relationship is different.

The outer guide rail 31 guides and regulates the guide roller 14 from the outside of the circulation path of the guide roller 14 with a transfer surface 31a, and is fixed in a closed oval shape, bypassing the sprocket wheels 3 and 4 respectively. be done. On the other hand, the inner guide rail 32 connects the guide roller 14 to the guide roller 14.
It guides and restricts the flow from inside the circulation path, and is fixedly installed in a closed oval shape, bypassing the sprocket wheel 3.4. These outer guide rails 31 and inner guide rails 32 are arranged along the path 8 in the same manner as explained using FIG. 4 above.

Of course, even in this case, an effect equivalent to the above-mentioned effect can be obtained.

Next, two other embodiments in which a sliding member 62 is interposed between the suspension shaft 61 and the slit hole 57 will be described with reference to FIG. Here, a sliding member 6 with a sliding surface 63°63 is shown.
2 is slidably engaged with the slit hole 57, and a suspension shaft 61 passes through the sliding member 62. Sliding surface 6
It is clear that if a wear-resistant anti-friction material is used for 3.63, the sliding resistance will be reduced, and it will also be easier to replace when wear occurs. In other respects, this case is completely equivalent to the above case.

Next, three other embodiments in which the path 78 of the carrier is partially different will be described with reference to FIG.

In the configuration explained with reference to FIG.
, D, E, and F points are circular arcs, but in concretely applying the present invention, the curve sections are not necessarily limited to circular arcs. In other words, when it is desired to limit the area of interference between the carriers to the sides or above of the carrier frame as the carriers move, the above-mentioned curve section may be combined with two or more circular arcs with different radii of curvature, if desired. curve, or
This can also be achieved using curves expressed by various functions. However, it is clear that the curve in these cases must be formed so as to go around the sprocket, and the line 8 must not deviate from the range of the slit hole 7.

Here, the curve section shown in FIG. 8 will be explained as an example where the curve section is not composed of only a single circular arc.

Below the sprocket wheel 74 are C', D', and E'F'.
A curved section path 78 passing through the points is formed. Here, the arc between points C' and D' is an arc, and the arc between points E'F' is also an arc, but a horizontal elapsed section is interpolated between points D' and E'. In the figure, the chain arm 76 is shown at point D' and point E' for explanation, but it is not located at both points at the same time, but is shown as having moved over time. This is what is shown.

In this configuration, the height of the guide roller 84 to the suspension shaft 81 is constant between points E' and D', so the height of the carrier (not shown) suspended therefrom is also constant. It is maintained.

In general, in a normal vertical circulation type parking device, the braking distance is affected by load imbalance, etc., and the stopping position of the carrier at the entrance/exit may deviate from side to side. However, in the case of this embodiment, if the carriage stops at least between points D'E', no vertical movement of the carrier will occur, and therefore, a step will not occur. It can be done.

In this case, of course, the configuration should be taken into consideration so that the area of interference between the carriers does not become large. Furthermore, in this embodiment, the horizontal section between points D'E' is a straight line, which is similar to points A, B, and C in Fig. 4.
Between points and F, G.

Of course, the straight line section described in the gist of the present invention, which is arranged in the vertical direction between points H, is a material.

[Effects of the Invention] By using the device of the present invention, the width or frontage of the parking device can be reduced.

For example, - According to the numerical design example, the width dimension of a conventional standard vertical circulation parking device can be shortened by about 500 seconds. In addition, interference between the carriers near the upper and lower sprocket wheels can be reduced, allowing safe operation.

Mechanical parking devices can be located in areas with high land prices, and in such areas, where it is often difficult to obtain suitable land or locations for installing parking devices, land width Although installation of a parking device may have to be abandoned due to a slight shortage of parking devices, the present invention makes it possible to install a parking device even in such a case. Furthermore, by reducing the frontage of the parking device, it becomes possible to effectively use the freed-up land for other purposes, even if only a little.
